-COAL-HOD.

SPECIFICATION forming part of Letters Patent No. 279,871, dated June 19,1883.

' Application filed March as, 1883. (No man.)

To all whom it may concern:

Be it known that I, CHARLES Horn, a citizen of the United States,residing at Cincinnati, county of Hamilton, State of Ohio, have inventedcertain new and useful Improvements in Coal-Hods, of which the followingis a specification.

My invention relates to coal-hods and similar sheet-metal vessels. Itsobject is to produce IO a stronger and better article than those incommon'use at a less cost of labor and material.

With this object in view my invention consists in forming the bucketfrom a blank so shaped as to be bent into a cone or funnel shaped body,then folding the cone end of said body in crimps to form the bottom, allof which will be fully understood from the following description of ti1e accompanying drawings. in which Figure 1 is a perspective view of acoal-hod constructed according to my invention. Fig. 2 is a top planview of the same. Fig. 3 is a side elevation of the blank formed into acone or funnel shaped vessel, the bottom part showing in dotted linesthe preliminary corrugations, indicating lines on which the metal willbe crimped and folded down to form the bot tom. Fig. 4 is a centralvertical section of the completed bucket or hod. Fig. 5 is the goblankfrom which the body of the bucket is formed.

, Similar reference-letters are used to indicate identical partswherever they occur throughout the various views.

The blank A, Fig. 5, being cut out to the shape shown, is bent around acone-shaped former and the edges 0 a. united in any suit able manner.This brings the blank to the form shown in Fig. 3. After the seam hasbeen made the partially-formed blank, Fig. 3, is placed upon a formerhaving its end grooved or turned off in steps below the'line w m, asshown in dotted lines, Fig. 3. Then, by suitable clamping-jaws, themetal in the lower end of the blank is pressed to the shape of theformer, commencing at the upper edge or groove, and successivelypressing the metal into each groove in the former until the lower onehas been pressed in. After this operation has been performed the blankhaving the partially-folded bottom is placed and clamped upon a formerthe exact shape of the interior of the hod, the exterior clamping devicegraspingthebody of the hod just above the line 00 00. Then, bysubjecting the partially-crimped bottom to the action of a plunger, thecrimps are folded down flat, as shown in Fig. 4, thus completing thebodyof the hod. The base B, handle G, and bail D are attached in the usualmanner.

It will be seen that the surplus metal is taken up in the bottom whichin use sustains the most wear. The hod is therefore strengthened wherestrength is most needed. It will therefore last in use much longer thanthe common hod and can be produced at less expense.

I do not desire to limit myself to any particular form of crimp or foldfor the bottom of the hod, nor to the enact shape of the blank shown inFig. 5, for it is evident that the form of the fold may be changed andstill have the tapered end of the blank, Fig. 8, compressed to force thesurplus metal to fold over and strengthen the bottom, and also evidentthat '7 5 the blank may be varied to suit different shapes of hods. Ihave selected one-of the common forms to represent my invention. Tochange the blank to make a different form would be the work of amechanic and require no invention.

It is also evident that my invention is applicable to buckets, scoops,and many other vessels made of sheet metal.

What I claim as new, and desire to secure by Letters Patent, is-

1. The method of forming the body of a coal-hod or other similar vessel,which consists, substantially, as before set forth, in first forming acone-shaped body from a suitable blank, then folding in the cone end ofsaid body in crimps to form the bottom.

2. As a new article of manufacture, a coalhod formed of a single pieceand having its bottom crimped or folded to form a series of annular ribsor rings of progressively-increasing diameter, substantially as shownand described.
